Fraunhofer ISE optimizes propane heat pump technology

With the Green Deal, the EU has committed itself to becoming CO2 neutral by 2050. In Germany alone, the provision of heating and cooling makes up 40% of total final energy consumption. Efficient and sustainable key technologies, such as heat pumps, are therefore becoming increasingly important in driving the energy transition. The focus is on natural refrigerants, as it is highly likely that only such refrigerants as propane will be allowed to be used throughout the EU in the future. All conventional fluorinated hydrocarbons (PFAS) will no longer be available to the market.
